When resources are limited, populations exhibit logistic growth. A computer laboratory course where population and community ecology concepts are applied to real-world datasets and simulated data. In nature, populations may grow exponentially for some period, but they will ultimately be limited by resource availability. The graphing and data analysis portions were a favorite. In logistic growth a population grows nearly exponentially at first when the population is small and resources are plentiful but growth rate slows down as the population size nears limit of the environment and resources begin to be in short supply and finally stabilizes (zero population growth rate) at the maximum population size that can be supported by the environment (carrying capacity). According to the population growth graph, what can be determined about the population is that the carry capacity is around 0.4 million. \(r\) is the per capita rate of increase (the average contribution of each member in a population to population growth; per capita means per person).
